Traffic-aware GTS Allocation Interval Determination for IEEE 802.15.4 DSME Networks

In this paper, we propose a traffic-aware guaranteed time slot (GTS) allocation interval determination (TaAID) for IEEE 802.15.4 deterministic synchronous multichannel extension (DSME) networks. TaAID aims to allow each coordinator to determine its GTS allocation interval. TaAID allocates allocation order to each coordinator based on its traffic load, which depends on the hop count and the number of child devices within the cluster. The simulation results demonstrated that TaAID outperformed the legacy DSME in terms of aggregate throughput and average end-to-end delay.
